I believe the GEMPAK decoders are very particular on the format of the
file. The dctaf decoder is expecting the data to have the embedded
control characters and headers as they are transmitted across NOAAPORT.
The first thing it parses for is a crtl-A indicating a start of a bulletin,
though there may be some bizarre alternate sequence - something like ZCZC.
I think it also needs the lines terminated with CR CR LF.

I am trying to decode the attached raw taf file using dctaf, but am getting nothing. I'm using the following command line and get the log file below. I guess the way I understood is that dctaf can be used to decode the raw data. Any help would be great. Thanks.
